The 23-year-old singer chatted with the medical glossy about her new album, fitness routine and always keeping a positive outlook on things. Check it:

On Red: “I’m really proud of the record, but I’m always nervous about everything. There’s a great deal of terror that fills my mind before I do anything, really. We’re talking before an album comes out, before a photo shoot, anytime I read my name in print. There’s a huge amount of pressure and responsibility because millions of people are going to potentially spend their hard-earned money on the album, and there’s a great responsibility for the critics who will write about it, and responsibility for the girl who is going through a breakup and needs a song about what she’s feeling, and responsibility for the girl who doesn’t feel good about herself and needs a song for that, too, and I worry about saying or doing the wrong thing.” Swift pauses for a breath and laughs. “Do you see the rabbit holes I go down?”

On working out: “I like to feel really tired afterward, sweaty and disgusting. I don’t care about losing weight as much as feeling good about myself. You can’t indulge without exercising, so I exercise because I love eating and I don’t want to have to live without anything. But I also exercise because on the occasional days when I’m feeling low, it always makes me feel better.”

On her 23rd birthday and the advice she would’ve given herself: “I wouldn’t tell myself anything because I’ve learned so many things in the last two years by experiencing them fully, and learning the lessons completely. Advice wouldn’t have changed that, but even if it might have, the best way to learn lessons is by going through things completely. No matter what path my life follows, I’m always going to be exploring every aspect of human emotion. And I’ll always want to get better…at everything.”
